Texas recently faced one of its most significant health challenges in decades: a major measles outbreak that started in early 2025. While state health officials officially declared the West Texas portion of the outbreak over in August 2025 after 42 days without a new case, the impact of this event continues to shape public health discussions in 2026. This guide explains what happened, the symptoms to watch for, and how you can protect your loved ones.

What Happened in the Texas Outbreak?

The 2025 Texas measles outbreak was a stark reminder of how quickly a nearly forgotten disease can return. It began in late January 2025 and primarily hit West Texas counties like Gaines, Lubbock, and Dawson. By the time the primary outbreak was declared over, officials had confirmed 762 cases.

This was the largest number of measles cases Texas had seen since 1992. The virus spread rapidly through communities with lower vaccination rates. Sadly, the outbreak led to 99 hospitalizations and two deaths in school-aged children. These children were unvaccinated and had no known health problems before catching the virus.

Why Measles is Making a Comeback

For years, many people thought measles was a thing of the past. The United States officially eliminated measles in 2000 because of high vaccination rates. However, elimination doesn’t mean the virus is gone forever; it just means it isn’t spreading constantly within the country.

When vaccination rates in a specific town or county drop below 95%, “herd immunity” breaks down. This creates a gap that the virus can jump through. In the Texas outbreak, some areas had vaccination rates well below this safe level, allowing the virus to spread like wildfire once it was introduced.

Recognizing the Symptoms

Measles is much more than just a skin rash. It is a serious respiratory infection that starts with symptoms that look like a bad cold. Knowing the timeline of the illness can help you get help early.

The First Signs (Days 1–4): The illness usually starts with a high fever, a hacky cough, a runny nose, and red, watery eyes.
Koplik Spots: Two or three days after the first symptoms, tiny white spots might appear inside the mouth. These are a unique “warning sign” of measles.
The Rash (Days 3–5): A red-brown rash typically begins at the hairline and face. Over the next few days, it spreads down the neck and trunk to the arms, legs, and feet. When the rash appears, the fever can spike to over 104°F.

Why It Is So Dangerous

Measles is one of the most contagious diseases in the world. If one person has it, 9 out of 10 unvaccinated people who are near them will catch it. The virus can even hang in the air for up to two hours after an infected person has left the room.

While most people recover, the complications can be severe:

Pneumonia: This is the most common cause of measles-related death in children.
Encephalitis: This is a dangerous swelling of the brain that can lead to permanent damage.
Ear Infections: These can result in permanent hearing loss.

How to Stay Protected

The best way to prevent measles is the MMR (measles, mumps, and rubella) vaccine. It is highly effective; two doses provide about 97% protection for life.

During the 2025 outbreak, Texas saw a surge in people heading to clinics to get vaccinated. Health departments even offered “early” doses for infants in high-risk areas. If you aren’t sure about your family’s vaccination status, check with your doctor. It is safe to get a “booster” dose if your records are missing.

Looking Ahead to 2026

As of early 2026, health experts are watching for “spillover” cases from neighboring states like South Carolina, which is currently experiencing its own large outbreak. The lesson from Texas is clear: the virus is still here, and it looks for any community where protection has weakened. Staying informed and keeping up with routine vaccinations is the best way to keep your family and your neighbors safe.
